1. THE METHOD OF PREPARING A SOLIDIFED END ON AN INSULATED, STRANDED CONDUCTOR, COMPRISING THE STEPS OF: SEPARATING A PORTION OF THE INSULATION ON THE STRANDED CONDUCTOR END FROM THE REMAINING INSULATION, PARTIALLY WITHDRAWING THE SEPARATED PORTION OF THE INSULATION FROM THE REMAINING INSULATION SO THAT AN AREA OF THE STRANDED CONDUCTOR IS EXPOSED THEREBY AND THE CONDUCTOR STRANDS ARE RETAINED IN A SUBSTANTIALLY GROUPED ARRANGEMENT, DEPOSITING MOLTEN SOLDER ABOUT THE EXPOSED STRANDS OF THE CONDUCTOR SO THAT THE EXPOSED AREA IS SUBSTANTIALLY SOLIDIFIED UPON COOLING OF THE SOLDER, AND SEVERING THE STRANDED CONDUCTOR IN THE SOLIDIFIED AREA, THEREBY PROVIDING A SOLIDIFIED CONDUCTOR END.
 7. AN APPARATUS FOR PROVIDING A SOLIDIFIED END ON AN INSULATED STRANDED CONDUCTOR, COMPRISING MEANS FOR SEPARATING A PORTION OF THE INSULATION ON THE CONDUCTOR END FROM THE REMAINING INSULATION, MEANS FOR PARTIALLY WITHDRAWING THE INSULATION REMAINING BETWEEN THE REMOVED PORTION AND THE CONDUCTOR END SO THAT AN AREA OF THE STRANDED CONDUCTOR IS EXPOSED THEREBY AND THE CONDUCTOR STRANDS ARE RETAINED IN A SUBSTANTIALLY GROUPED ARRANGEMENT, MEANS FOR DEPOSITING A BINDING MATERIAL ABOUT THE STRANDS OF THE CONDUCTOR IN TH EXPOSED AREA SO THAT THE EXPOSED AREA IS SUBSTANTIALLY SOLIDIFIED, AND MEANS FOR SEVERING THE CONDUCTOR IN THE SOLIDIFIED AREA THEREBY PROVIDING A SOLIDIFIED CONDUCTOR END.
